I think you have to add Edmonton to the annoying little brother club.
The Western Cities are all irrationally hostile to Toronto the city. This is a historical thing stemming from our traditional political and economic dominance. Elections are decided before they are done voting so they have always felt marginalized and overlooked which has lead to numerous political movements like the Reform party and the Social Credit. Toronto is the biggest city in the Country and Ontario the largest and historically the richest province. The Oil boom out west did not last long enough for them to gain any political ground on the country. So you have a culture of resentment before sports ever entered the conversation.
Now when we move on to Hockey we have the largest market, the richest team, we dominate national media coverage and we have a fan base larger than all of them combined. We invade their home games when we come to their town because there are Leaf fans in good number all across both countries (but Canada in particular) so there is always a presence.
Buffalo actually suffers more from Leaf fan invasions because it's so close and we are always plotting of ways to steal their football team. The last try in particular seems to have touched a nerve. They already have enough problems with being overshadowed due to their proximity to New York City. How do they feel when there are more Leaf fans than Sabres fans at their home games?
Now add to all this the HF element.
I would guess we make up 40%+ of the fans here. So we have about 10 times more idiots than any other fan base and people who lack self control. We dominate any thread that interests us, many of our fans over rate everything to do with the Leafs and cannot pass up a chance to boast.
Even now we have fans saying we have all but beat Washington and Matthews is better than McDavid, things that would not be well received coming from any team let alone us.
Kapanen scores and we have a thread about if our 4rth line is the best.
Someone is rumoured to be on the trade market and we flood the proposal threads with stupid offers.
Often the valuations of our players that are presented to outsiders are foolish and delusional and we have a history of overvaluing our prospects.
Now these things in and of themselves are harmless but add them all up and add the sheer volume and it can often be overwhelming and outright annoying to other fans.
In our defense we have had pretty good valuations on our trade deadline returns the last few years and our rookies have all lived up to the hype. We won the lottery and got St Matthews who exceeded the insane expectations we gave him. Heck our team even did way better than most of us thought it would sneaking into the playoffs when the experts said we would be fighting for last. Now we are making the Caps nervous.
Our rivals loved us being down and out because we were easy to kick around, but when we look at our list of annoying little brothers a lot of them are having tough times while we are having the miracle year. Vancouver, Winnipeg and Buffalo are in the outside looking in while we wonder if we'll get to the 2nd round and how much better our kids will be next year.
Auston alone with his 4 goal first game, 40 goal season and Calder trophy(probably) is the last thing you want to see happen to us on a youth obsessed forum like this, not to mention Marner, Nylander, Zaitsev, Brown (who they all told us was garbage) and now Kapanen.
We are enjoying a perfect storm and that is very frustrating to the people who desperately only want bad things to happen to us because that is the source of their happiness. It's hard to feel bad for them but it would be nice if some of our fans could be more diplomatic, less prone to "tell us how great we are" threads and were a little less cocky. At this point though, it is hard to feel sorry for them.
Nothing is more frustrating than when someone you hate or find very annoying seems to get every break which is the wave we are riding right now.
On a side note I think that radio guy is involved in the Matthews vs Eichel thread
